Somewhere in the bogland of Lullymore, in County Kildare, a cross once stood that has since been moved from its original position, leaving behind little more than a coordinate and a catalogue number. What remains on record is the presumed original location, a spot that now carries significance mainly by absence, marking where something was rather than where it is.

The cross is identified in the scholarship of M. Kelly, catalogued in a 2006 study as "Cross 8", one of several crosses associated with the Lullymore area. Lullymore sits within the great raised bog of the Bog of Allen, a landscape with early medieval ecclesiastical connections; the island-like dry ground amid the surrounding bog made it a logical place for early Christian settlement and the erection of stone markers. The cross itself was later recorded at a separate location, suggesting it was at some point relocated, a fate not uncommon for early medieval stone monuments, which were frequently moved in later centuries for practical or devotional reasons, or simply because the land around them changed hands and use.
